as part of my science homework we have to give an example of a rock which is soft and easily scratched but I don't know what rock that is please help?
A very soft rock like gypsum or talc would be scratched easily with a finger. Rocks like quartz, granite, or diamond would not be scratched by a finger.
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.
Minerals that are soft enough to be scratched by a fingernail include gypsum (2 on the Mohs scale), talc (1), and calcite (3).
Oklahoma rose rock has a hardness of around 2.5-3 on the Mohs scale of mineral hardness. This means that it is relatively soft compared to other minerals and can be easily scratched by harder materials.
The rock you are referring to is talc, which is a soft metamorphic rock composed mainly of the mineral talc. Talc is known for its greasy or soapy feel and is commonly used in cosmetics and as a lubricant.
soapstone

Soapstone is a metamorphic rock composed of the mineral talc. Soapstone is a non-foliated metamorphic rock with a microcrystalline texture. It is very soft and can be easily scratched.
Calcite perhaps (although it does not form cubes).
Because it is soft
The rock type that can typically be scratched with a fingernail is sedimentary rock, particularly soft varieties like limestone or chalk. These rocks generally have a hardness of 2 to 3 on the Mohs scale, making them softer than a fingernail, which has a hardness of about 2.5. This property allows for easy scratching and is a useful field test for identifying rock types.
no, it does not flow out of the spout eaisly
I do not know. But hitting a rock, gold would lose.
Certainly not; gold is very soft.
